In Great Britain January 22, 1932 16 Claims. (c1f1o1-221) This inventionrelates to improvements in or relating to late news and like mechanismfor use in printing machines, and has for its principal object'theprovision of improved means whereby the substitution of one late newsform for another may be achieved without stopping the printing machineduring the run of an edition.

Another object is to provide improved means for equalizing the speed ofeither of .a. pair of printing cylinders with the speed 'of a meetingimpression cylinder, and for providing circumferential register betweenthe said cylinders. A further object is to provide the combination ofclutch-operated means for connecting the printing cylinder in driveconnection with the impression cylinder, with means for automaticallyeffecting the release. of a brake which normally holds the printingcylinder stationary.

It is also an object of the invention to provide a late news device ofgenerallyimproved construction, whereby the device will be simple,durable and inexpensive in construction, as well as convenient,practical, serviceable and efilcient in its use.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination and.arrangement of parts, and in the details of construction hereinafterdescribed and claimed.

30 Ihe invention is illustrated in the accompanying drawings as appliedto arrangements in which there are employed a plurality of printingcylinders arranged for independent cooperation with a common impressioncylinder although it 35 is to be understood that the invention is notconfined in its application to the employment of a plurality ofindependent printing cylinders.

Referring more particularly to. Figures l-6, Lisan impression cylinderand 2, 3 late news printing cylinders which are adapted to cooperateindependently with the impression cylinder, each printing cylinder beingmounted upon a shaft 4. The term printing cylinder? is intendedtoincludethe employment ofa group ofcylinders a'ranged to be actuatedtogether, and such an arrangement as illustratedin Figure 1 in whicheach shaft 4 has thereon two printing, cylinders. The' mechanismhereinafter described is duplicated for each late news printing cylinderand the following. description of one will apply to the other. l 40 Eachshaft 4- is supported in eccentric bushes 5 which can be causedpartially to rotate to move its printing cylinder into and out ofprinting position by means of a transverse shaft 6 extending from oneside of the machine to the other and connected to the bushes v5 bylinks 1. One. terminal of each link 'lis pivotally connected to anarm I?secured to the shaft 6, and the opposed terminal of the link ispivotally connected to an ear 5' formed on the flange of the eccentricbushing 5. Movement of the shaft li'is eflected through self-lockingworm and. worm wheel gear- 1 ing 9 by means of a hand. wheel 8, the wormwheel being fast onthe shaft 6. The movement: of the cylinder intoimpression position is regu- 28 is provided with a disc 32 having itsperiph- 29 to ice-applied. This operation will cause they lated bystationary adjusting screws l0, and it will be seen that movement of thecylinder into and out of impression does not affect the setting of theadjusting screws Ill, so that it is ensured that the cylinder willalways be returned to that degree of impression pressure from which itwas moved.

The shaft 4 is arranged to be driven from the impression cylinder shaftthrough gears ll, [2, and, in order to effect speeding up of the shaft,the gear I2 is freely mounted on the shaft 4 and is provided with aplate l3 having spindles I 4 on which are mounted planet pinions l5.These planet pinions mesh with a gear l6 formed on a sleeve I! securedto the shaft 4 having a drum l1 whose periphery is arranged to beengaged by a brake band l8. The sleeve l1 and drum I1 are securedagainst rotation relative to the shaft 4 and to each other by means of akey or feather II. The pinion also meshes with an internal gear I9formed on a drum l9 rotatably mounted on the sleeve II, and a secondbrake band is arranged to engage a boss 2| formed as an extension of thedrum H3. The brakes l8 and 20 are controlled simultaneously by cams 22,23 on an operating rod.24 adapted to be actuated by a lever 25; the camsare so displaced relatively to one another that when one brake band isapplied the other is released and vice versa. The lever 25 is connectedby alink 26 to a pin mounted eccentrically on a disc 21 fast on a shaft28 having secured thereto a worm wheel 29 in mesh with a worm 30arranged to be'ro'tated by a hand wheel 3|.

In order to prevent the printing cylinder from being moved intoimpression position until it has been speeded up to the speed of theimpression cylinder, and, conversely, to prevent the drive to thecylinder from being disconnected before it has been moved out ofimpression, the shaft ery cut away to provide an arcuate recess 32 toreceive in only one position the arcuate portion 33a of a mutilated disc33 secured to the shaft 6 which through the disclosed instrumentalitieseffects movement of the printing cylinder into and out of printingposition; also secured to the shaft 28 is another disc 34 whoseperiphery is cam shaped so as to operate a lever 35 which is connectedto a locking plunger 36 adapted to enter one or other of a pair ofrecesses I So formed in the drum IS, the lever 35 being urged towardsthe cam by a spring 31.

In operation, assuming that the printing cylinder is out of printingposition, in which position the brake band I8 is on so that the drum l1and sleeve I1 and thus the shaft 4 are rendered stationary, and thebrake band 29 is off if it be desired to move the cylinder into printingposition, it is first necessary to rotate the shaft 28 to therebyoperate the brake bands l8 and 20 so as to cause the gears H and I2, andthe planetary gears I5, l5 and 19 to effect speeding up of the printingcylinder before the cut away portion or arcuate recess 32 of the disc 32will move into position to receive the arcuate portion 33 of themutilated disc 33 to permit the shaft'fi to be rotated to move theprinting cylinder into printing position. Rotation of the shaft 28causes the brake band 8 to be released and the brake band drum 19 toslowdown and finally to stop so that the gears l2, l5, l9 and [6 willdrive the sleeve I 1 and thus the shaft 4'. The drum I9 is locked in adefinite position by the plunger 36 so as to ensure circumferentialregistration of the printing cylinder, because with regard to theimpression cylinder the plunger 36 can only enter into a recess lSa inlooking position when the drum I9 is in definite or predeterminedpositions. When the shaft 28 has been actuated in the manner describedto speed up the printing cylinder, the arcuate recess 32 of the disc 32lies in a position such that the arcuate portion 33 of the mutilateddisc 33 can be moved therethrough. Movement of the shaft 6, which iseffected by the hand wheel 8, causes the eccentric bushes 5 partially torotate and thus to move the cylinder into impression position, thepressure being determined and limited by the adjustment of the screwsID.

The arcuate portion 33 of the disc 33 is positioned in the arcuaterecess 32 of the disc 32 when the late news cylinder is in printingposition, therefore it is necessary to rotate the shaft 6 and thuseffect movement of the eccentric bushes .5 to move the cylinder out ofprinting position before the shaft 28 can be rotated to disconnect thedrive to the cylinder. i

It will be seen that each of the two printing cylinders can be operatedindependently. The arrangement according to the invention iscomparatively simple, the planetary gear will ensure smooth and positiveaction and avoids the setting up of end thrust, and the provision of thesecond brake band enables the printing cylinder to be braked by movementof the same member (i. e. the member 24) which controls the drive.

In the modification illustrated in Figures 7-12, there is employed amodified form of mechanism for interlocking the movement of thecylinders into and out of printing position and the speeding up of thecylinders.

In this modification (which, as in the arrangement first referred to,will be described in connection with one printing cylinder, 2. similararrangement being employed for the other cylinder) the gear wheel ll isin mesh with a gear 38 which is loosely mounted on the shaft 4 and isprovided with one part 39 of a friction clutch of the plate type; theother part 49 of the friction clutch is slidably mounted on a block 4|secured to the shaft, and the part 49 of the clutch is urged by aplurality of springs 42 and is controlled by bell crank levers 43. Thelevers 43 are, in turn, controlled by a sleeve 44 slidably mounted on anextension of the shaft, this sleeve being provided with recesses 45adapted to receive bowls or rollers 46 mounted on the bell crank levers;this sleeve is also provided with a pin 41 which is urged by a spring 4]so as to be adapted to snap into a bushed aperture 48 formed in the gear38. Movement of the sleeve is effected through an actuating trunnion 49which can be rocked by means of a link 59 pivotally mounted on a pin 5!eccentrically secured to a worm wheel 52 in mesh with a, worm 53operable by a hand wheel 54. In this arrangement also the worm wheel 52,which is operably supported by a shaft 52, is fast through the shaft 52with a disc 55 having a cut away portion 56 which is arranged tointerlock with a flange 51 also having a cut away portion 58, the flangebeing secured to the shaft 6* by movement of which the cylinder is movedinto and out of printing position. The worm wheel 52 is also fastthrough its shaft 52* with an eccentric pin 59, connected by a link 69to a bell crank lever B! which operates through a collar 62 on a rod 62'to apply or to release a brake 63 from a brake drum 64 secured to theshaft 4 This rod 62' is also connected to a transverse foot bar 65 whichextends substantially from one side of the machine to the other.

Interposed between the worm wheel 52 and the disc 55 is a sleeve 66having mounted thereon a latch 61 which can drop into, when the partsare in and out of printing position respectively, one or other of a pairof notches 68 formed in the disc 55.

In this modification, the parts for effecting movement of the cylinderinto and out of printing position are substantially the same as thosedescribed with reference to Figures 1 to 6, except that additionallimiting screws ID are provided for limiting the movement of thecylinder out of printing position. Certain components are illustrated inthis modification, and inasmuch as their functions have beenhereinbefore disclosed in the description of the form of the inventionillustrated in Figures 1 to 6, these components are designated byreference characters similar to those employed in Figures 1 to 6 butwith the addition of exponent a.

. In operation, assuming that the printing cylinder is in itsnon-printing position, the part 40 of the clutch and also the pin 47 arein their disvice to effect speeding up of the printing cylinder 7 beforethe cut away portion or recess 56 of the disc 55 will move intoalinement with the flange 51 to allow rotation of the shaft 6 to movethe cylinder into printing position. Rotation of this hand wheel 54will, through the link 50 and trunnion 49, cause the sleeve 44 to moveto the right so as to allow the bowl or roller 46 to drop into therecess 45 formed in the sleeve 44; this movement allows the springs 42to throw the part 40 of the clutch into engagement with the part 39, andthus the shaft 4 and hence the printing cylinder will be speeded upthrough the friction clutch. Further movement of the hand wheel 54 willcause the sleeve 44 to depress the lever 43 and thus cause the part 40of the clutch to be disengaged. The pin 41 which is now pressed by itsspring 41' against the face of the gear 38 is now in a position to snapinto the recess 48 formed in the gear when, by reason of the slightrelative movement between the two parts of the clutch, the recessovertakes the pin. Thus it will be seen that the printing cylinder isfirst speeded up through the friction clutch 39, 40 and then positivelydriven through the pin 41 in a definite relationship with theimpression'cylinder.

At this stage of the operation the cut away part or recess 56 of thedisc 55 is in line with the flange 51 on the shaft 6 which can now beturned to cause the cylinder to be moved into impression position bymovement of the eccentric bushes, as described with reference to Figures1-6, .Similarly when the cylinder is in printing position it isnecessary to move it to its non-printing position before the cut-awaypart or recess 58 on the flange 51 moves into alinement with the disc 55to allow the drive to be disconnected.

Before any control can be exercised upon the cylinder drive it isnecessary to lift the latch 61 to allow the hand wheel 54 to be turned.

In a modification shown in Figures 13 and 14 the friction clutch is inthe form of semi-circular internally expanding brake shoes 69, which arenormally urged by springs H to engage the interior surface of a boringformed in the gear 38.

Movement of the clutch into and out of clutching position is. under thecontrol of a lever 12 pivotallymounted at 13 and provided with a bowl orroller 14 which is under the control of a sleeve 44, as inthearrangement described with referr5 ence to Figures 7-12.

It will be seen that with'the arrangements described in Figures 7-14,the reaction to the pres-. sure of the springs 42 or H is taken radiallyby the sleeves 44 or 44 so that no end thrust is ex- 10 erted; and themovement of the sleeve being at right angles to the line of thrust caneasily be effected. 1

In the modification shown in Figure 15, a differential gear is employedfor effecting speeding 1 57 up of the printing cylinders. In thisarrangement the gearlZ is secured to a sleeve 15 having a flange 16carrying the cage 11 of a differential gear, the pinions 18 of which arerotatably mounted on axles 19 carried by the cage: these 201: pinionsare in mesh wtih gears 80, 8| of which the gear 80 is fast with theshaft 4, and the gear 8| is fast with the brake drum 82, the two brakesl8 20 being arranged as has been described.

The drum 82 is arranged to be engaged by a 25:2 locating pin 36, as hasbeen disclosed in the description of Figures 1 to 6. It will be seenthat the operation of this difierentialgear arrangement is similar tothe operation described with reference to the planetary gear of Figures1 6, 30"- ent embodiments be considered in all respects 35- asillustrative and not restrictive, reference be ing had to the appendedclaims rather thanto the foregoing description to indicate the scope ofthe invention. 7 I
